What is an 80 Platinum power supply?
The 80 PLUS program tests computer power supplies for efficiency at 20\%, 50\% and 100\% loads. Initially, power supplies only needed to be 80\% efficient to earn certification. Over the years as power supplies became more and more efficient, new standards such as Bronze, Silver, Gold, and Platinum were created.
What does 80 Plus Platinum mean?
80 Plus Platinum: 90\% efficiency @ 20\% load; 92\% efficiency and power factor of 0.95 @ 50\% load; 89\% efficiency @ 100\% load.
What is 80 Plus in power supply?
The 80 Plus is a voluntary certification where manufacturers send samples of their power supplies to an independent body for testing and certification. To be 80 Plus certified, the supply must have at least 80 \% efficiency at three load levels of 20, 50 and 100 percent of loading.
What is a Platinum rated power supply?
Platinum-level power supplies are 90-100\% more expensive; twice the price of a standard 80 Plus unit. By way of example: Antec and Rosewill have $50-$60 80 Plus PSUs in the 501-600W category, while the 80 Plus Platinum products are $139 and $110 respectively.
What is the best efficiency rating for a power supply?
Most power supplies hit their peak efficiency levels with loads in the range of 40 to 80 percent. Building to about 50 to 60 percent of a PSU’s capacity is advisable to achieve maximum efficiency and yet leave room for future expansion.
What is the best 80 plus rating?
The Current 80 PLUS Levels

- 80 PLUS.
- 80 PLUS Bronze.
- 80 PLUS Silver.
- 80 PLUS Gold.
- 80 PLUS Platinum.
- 80 PLUS Titanium.
What PSU rating should I get?
An efficient PSU is a better PSU A power supply with an efficiency rating of 80 percent provides 80 percent of its rated wattage as power to your system, while losing the other 20 percent as heat. Five of 80 Plus’s certification levels. Look for units with “80 Plus” certification.
Is 80 Plus Platinum better than gold?
80 Plus Gold PSUs are rated to deliver at least 90\% efficiency at 50\% load, while 80 Plus Platinum are rated to deliver 92\%. So, you would be looking at about a 2\% difference in the amount of power that the PC draws from the wall.
What is the best 80 Plus rating?
Is 80 Plus white good?
80 Plus “White” (Otherwise known as “80 Plus”) is the lowest (worst) 80+ rating there is. (EDIT: This does NOT mean it’s a bad power supply necessarily, there are plenty of PSUs that have NO 80 plus certification. It just means that it’s a bit less efficient than other power supplies with better ratings.)
Is 80 plus white good?
What does 80 plus mean on a power supply?
What Does 80 Plus Mean? The 80 Plus system is set up to rate the efficiency of power supplies. Every power supply certified by the 80 Plus standard is at least 80-percent efficient at 20-, 50-, and 100-percent of load, hence the name.
What is the power efficiency of a titanium PSU?
Indeed, the introduction of the 80 PLUS Titanium standard brought a fourth measurement into the certification mixture: efficiency at 10\% rated load. Also, with Titanium, PF needs to be at least 0.95 at a lower load level (20\% of the PSU’s max-rated capacity).
What are the different levels of power supplies?
Over the years as power supplies became more and more efficient, new standards such as Bronze, Silver, Gold, and Platinum were created. Below are the different 80 PLUS levels and the efficiency requirements for each level:
What is the power factor of 80 plus titanium?
80 Plus Titanium: 90\% efficiency @ 10\% load; 92\% efficiency and power factor of 0.95 @ 20\% load; 94\% efficiency @ 50\% load; 90\% efficiency @ 100\% load. You’ll notice that the distinctions between various levels of 80 Plus seem small.
